Senator Patrick Leahy from Vermont Advocates For The Mosquitia

Today United States Senator Patrick Leahy advocated for the preservation of the ecological and cultural patrimony of the Mosquitia.  Reacting to President Hernandez’s recent announcement for increased protection in the area, Leahy stated in part

“President Hernandez’s commitment to preserve these archeological sites from looters and other criminal activity and to protect the broader forest area by replanting the jungle and countering deforestation deserves our support. I look forward to working with the Government of Honduras on how the United States may be able to assist its conservation efforts.”

Chris Fisher Invited Speaker at the Tower of London for the CyArk 500

The CyArk 500 Conference

Chris Fisher, along with Steve Elkins – UTL, Juan Carlos Fernandez – NCALM,  and Virgilio Paredes Trapero – Director of IHAH, will be speaking on October 20-22 at the Tower of London on results and implications from the Mosquitia Honduras project.  At this event CyArk will formally launch the CyArk 500 Challenge to digitally preserve 500 cultural heritage sites within the next five years.  As part of their long-standing mission CyArk hopes to save these cultural heritage sites digitally before more are ravaged by war, terrorism, arson, urban sprawl, climate change, earthquakes, floods, and other threats. There isn’t enough money or enough time to physically save every site, but CyArk wants to use 3D technology to digitally save these sites to make them available for generations to come.

Should be a great venue to showcase our LiDAR efforts

LORE-LPB Project Members Aiding Search for Lost Cities in Central America

LORE-LPB Project Members Aiding Search for Lost Cities in Central America

A recent press release from Colorado State University

Note to Reporters: Print-quality photos of LiDAR images of the research area and CSU assistant professor of geography Stephen Leisz are available with the news release at www.news.colostate.edu.

FORT COLLINS – Colorado State University professors Christopher Fisher and Stephen Leisz have partnered with an international team of researchers utilizing LiDAR technology to seek ancient settlements and human constructed landscapes in an area long rumored to contain the legendary city of Ciudad Blanca – the mythical “White City” – in Central America.

The project is a collaboration of the Global Heritage Foundation (GHF), UTL Productions, the National Center for Airborne Laser Mapping (NCALM), CSU, and the Honduran government. It is outlined in detail in the May 6 edition of The New Yorker.

Fisher, associate professor of archaeology, and Leisz, assistant professor of geography, have successfully worked with airborne LiDAR to help reveal a lost pre-Columbian city in central Mexico. LiDAR (Light Detection and Ranging) is a remote sensing technique used to examine the earth’s surface.

Researchers focused their search for evidence of ancient settlements in the Mosquitia Coast region of Central America. Until now, dense tropical forests and relative inaccessibility of the region have hampered systematic archaeological investigation.

LiDAR’s computer-generated images allow researchers to “see” through the forest canopy to the ground surface, revealing any evidence of ancient settlements or human-engineered landscapes.

“The LiDAR point cloud data clearly show the remains of large settlements that can be characterized as ancient cities based on their spatial complexity, size and organization,” Fisher said. “We may never be able to tell whether any of these are Ciudad Blanca, or whether the legendary city ever existed, but we can clearly see in the UTL data evidence that there was a densely settled region with a human modified environment. These conclusions provide important new insights into the pre-Hispanic settlement of this largely unexplored region.”

Interpretation of the LiDAR data suggests that the largest of these settlements is roughly the size of the central core of Copan, Honduras, though the architecture appears to be much less monumental. Copan was a Mayan city of nearly 20,000 people that thrived from the 5th through 9th centuries A.D.

Fisher and Leisz utilized LiDAR in recent research documenting the extent and spatial organization of the newly discovered ancient city of Angamuco, Michoacán, Mexico, as part of the Legacies of Resilience Archaeological Project, sponsored by the National Science Foundation, NASA, and the National Geographic Society. Fisher, Leisz and several co-authors championed the use of LiDAR in Mesoamerica in a recent article in the Proceedings of the National Academy of Sciences as a scientific revolution that will fundamentally change the way that archaeologists do fieldwork.

“We were able to use our work at Angamuco to help reveal similar patterns in the Mosquitia data,” said Leisz. “The Honduras LiDAR results add to a growing number of studies using LiDAR point cloud-derived elevation data to analyze the ancient human impacts on the landscape of the Americas.”

Over the next several months Fisher, Leisz, and NCALM scientists will systematically analyze the Mosquitia data in preparation for fieldwork aimed at ground verification and documentation of the results as part of the broader GHF project. Leisz recently traveled to Honduras to sign a memorandum of understanding between CSU and GHF, as well as agreements of collaboration with The Honduran Institute of Anthropology and History (IHAH), and Porfirio Lobo, president of Honduras. Initial results from the project will be presented by Leisz and Fisher in a session on the use of LiDAR at the upcoming American Geophysical Union Meeting of the Americas, to be held May 14-17, in Cancun, Mexico.

The Lake Pátzcuaro Archaeological Project: Urbanism at Angamuco During The Postclassic Period

Cities form the core of modern society and a deeper understanding of the evolution of the urban form can potentially help to understand the modern world. One place that can make an important archaeological contribution to this debate is the Lake Pátzcuaro Basin, Michoacán, Mexico (LPB), which at the time of European contact was the core of the Late Postclassic (LPC) (A.D. 1350-1520) Purépecha Empire. This National Science Foundation award will fund a program of excavation at the newly discovered city of Angamuco to test models for the development of complex societies in the region. This project develops from over 3 years of NSF sponsored full-coverage survey (2009-2011) as part of the Legacies of Resilience: The Lake Pátzcauro Basin Archaeological Project (LORE-LPB). To test the models developed from this work researchers will excavate architectural complexes within two neighborhoods that, based on surface remains, had unique time and social associations.

Efforts will be focused on addressing three questions concerning the Angamuco occupation. 1) When was the predominate occupation of Angamuco and how does it relate to the development of complex societies in the region? 2) Can initial survey results concerning the function of individual structures and the spatial arrangement of these buildings be confirmed? Do domestic, public, storage, and ceremonial functions that inferred from surface remains conform with excavation data? 3) Can social differentiation be identified through excavation? If so, how does it evolve through time and how is this related to Empire formation.

Testing models that have been developed during the survey of Angamuco will substantially expand and deepen them and pave the way for future research. Results from this work will provide radiocarbon determinations that can help outline the timing, intensity, and location of the Angamuco occupation during the Postclassic. Stratigraphically dated assemblages from the Postclassic period will allow the creation of a more accurate ceramic chronology for this critical time interval. The refined temporal control will allow more accurately determination of the impact of Empire formation on the Angamuco polity.

The Angamuco case study can potentially yield important new insights into the development of complex societies in western Mexico, and in the process make an important contribution to anthropological understanding of the urban process. This is far from a simple academic debate in that global environmental change is increasingly placing urban dwellers at risk of increased poverty, displacement, and health risk.

Getting Ready for 2011 Fieldwork

The LORE-LPB project is gearing up for the 2011 season with more promising archaeology on the way.  By late May we hope to have LIDAR coverage for the site with the expectation that this should greatly increase the amount of area we are able to cover.  More exciting news is on the way.
